[Bug 47307] Re: Lots of windows needing Force Quit can hang metacity

[Brian Brunswick]

Yes, the wm was hung, it wasn't possible to change focus. It did seem to
hand over nicely to a new wm though I don't know whether the X protocol
for that needs the previous one to be alive.

It happened several times, but since then, I can't reproduce it with
latest updates, even though I've carefully not got around to fixing my
bug :-) It never really used to happen when I tried though anyway.

So who knows. I'll keep an eye out for it, and try to debug if I can.
